Problems solved by technology
However, when the ambient temperature is too high during use, causing the internal temperature of the camera module to rise, the circuit board in contact with the lens base is more likely to expand and warp, which will affect the stable holding of the lens barrel by the lens base, thereby affecting the image effect

A camera module includes a circuit board, an image sensor arranged on the circuit board, a lens barrel and a lens seat for holding the lens barrel. The mirror base includes a connection part fixedly connected with the lens barrel and a dustproof part connected with the connection part. The dustproof part encloses a containing space, and the image sensor is contained in the containing space. The mirror base also includes a fixing part connected with the dustproof part and accommodated in the receiving space. The fixing part is fixedly arranged on the image sensor. A first air hole is opened on the dustproof part. A second ventilation hole communicating with the interior of the camera module is opened on the fixing part. And the first air hole communicates with the second air hole so that the interior of the camera module communicates with the external environment. The above-mentioned camera module will not affect the stability of the lens base and the image effect due to the high internal temperature of the camera module.
Description
technical field [0001] The invention relates to a camera module. Background technique [0002] A general camera module usually includes a lens barrel, a lens clamped in the lens barrel, a lens holder for fixing the lens barrel, a circuit board, and an image sensor disposed on the circuit board. The outer side of the lens barrel has an external thread, and the inner side of the lens holder has an internal thread matched with the outer thread of the lens barrel. When assembling, first clamp the lens in the lens barrel, then screw the lens base and the lens barrel to fix it, then fix the image sensor on the circuit board and make it electrically connected, and finally align the lens and the image sensor The photosensitive center of the detector, and the mirror base is fixed on the circuit board. However, when the ambient temperature is too high during use, causing the internal temperature of the camera module to rise, the circuit board in contact with the lens base is more li...
